Coach Jorge Guerra, who pilots the Brazilian powerhouse, Bauru, wouldn’t predict victory in Wednesday’s matchup with the Knicks at the Garden, but he said Phil Jackson’s crew had better be prepared for a battle in its preseason opener.

Guerra and his coaching staff were at Barclays Center Monday when the Turkish power, Fenerbahce Ulker, upset the Nets and told The Post in Portuguese he was “not surprised.’’

“I think we can compete at an NBA level,” he said through an interpreter of his Brazilian League champs. “We definitely can match the Knicks. It’s a great challenge and they’re [a] more physical team, but we have an experienced team and our style of play is more aggressive in offense than European teams. We play more creative than Europe.’’

Guerra, a former Olympian, even fired a warning shot at Carmelo Anthony’s US Olympic squad, which is heading to Rio de Janiero for next year’s Summer Games.

“The last 10 years international basketball has taken a huge evolution,’’ Guerra said. “Everyone in the world can play. You got to respect every opponent. Team USA is favorite but if they’re not focused, they won’t get the gold medal as in the past.’’

Guerra played for the Brazil squad that posted a historic upset over Team USA in the 1987 Pan-Am Games. Wednesday, Guerra will trot out Brazilian Olympian shooting guard Alex Garcia, who played for the Spurs and New Orleans, and former Western Oregon forward Robert Day, his lone American.

There are an unprecedented nine Brazilians in the NBA, which is making an intensive push for basketball to become the second-most important sport in that country. Soccer is first, volleyball second. The Magic will play in Brazil Oct. 17 against Flamengo. Wednesday’s game with the Knicks will be televised in Brazil.

“For a Brazilian team to play in the world’s most famous arena is a big accomplishment for Brazilian sports,’’ said Philippe Moggio, the NBA’s senior vice president for Latin America.

Brazilian officials said core fans in the country have increased from 8 million to 9.5 million in the last year, but the retired Michael Jordan still is the most popular player.

“There’s a very big traction leading to the Olympics,’’ Moggio said.

Guerra said he has one of Jackson’s books with him that he’d like to get signed and said he has read three of Jackson’s tomes. “Guy with 11 rings is much respect. He was an excellent player, but a coaching idol,’’ Guerra said.

Knicks coach Derek Fisher said he’ll watch a little film on Bauru, which split games last month with Real Madrid.

“Our guys are excited,’’ Fisher said. “They’re tired of beating each other up. There’s been a lot of physicality, but it’s time to take some of it out on an opponent.’’

The Knicks’ 201-game sellout streak dating to 2010 is in jeopardy. The streak includes preseason, regular-season and playoff games. Tickets are still available for Wednesday’s game.

Fisher said Arron Afflalo (hamstring) won’t play and probably will sit out Friday’s Washington game, too.

“Hamstrings are tricky,’’ Fisher said. “We’re trying to be responsible.’’

The hiring of former Austin Spurs assistant Mike Miller as head coach of the D-League’s Westchester Knicks became official. He replaces Craig Hodges.
